PEMS08

We validate our model on the highway traffic dataset PeMSD8 from California. The dataset is collected by the Caltrans Performance Measurement System (PeMS) (Chen et al., 2001) in real time every 30 seconds. The traffic data are aggregated into every 5-minute interval from the raw data. The system has more than 39,000 detectors deployed on the highway in the major metropolitan areas in California. Geographic information about the sensor stations is recorded in the dataset. There are three kinds of traffic measurements considered in our experiments, including total flow, average speed, and average occupancy.

我们在加利福尼亚州的高速公路交通数据集PeMSD8上验证了我们的模型。该数据集由加利福尼亚州运输部性能测量系统（Caltrans Performance Measurement System，PeMS）（Chen等，2001）以每30秒一次的频率实时采集。原始交通数据经聚合处理后，得到每5分钟为一个时间间隔的统计数据。该系统在加利福尼亚州主要都会区的高速公路上部署了超过39000个交通检测器。数据集收录了各传感器站点的地理信息。本实验中共采用三类交通测量指标，分别为总流量、平均速度与平均占有率。
